LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 577,934, dated March 2, 1897.

Application filed October 22, 1896. Serial No. 609 ,660- (No model.)

To all whom, it m/lu concern:

Be it known that I, WALTER TODD, a citizen of the United States, residing in Paterson, county of Passaic, and State of New Jersey, have invented certain new and useful Improvements in Loom-Shuttles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawin gs, and to letters of reference marked thereon, which form a part of this specification,

My present invention relates to shuttles such as are usually employed in silk and other looms; and its object is to provide a tension and bobbin holding and controlling device of simple, strong, and durable construction, reliable and efiective in operation.

The invention consists in the improved shuttle, its tension and bobbin holding and controlling device, and in the combination and arrangement of the various parts thereof, substantially as will be hereinafter more fully described, and finally embodied in the clauses of the claim. 1

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several figures, Figure 1 is a plan view of my improved shuttle and its tension and bobbin holding and controlling device; Fig. 2, a front elevation of Fig. 1, and Figs. 3 and -il enlarged detail views of certain means for removably securing the bobbin-supporting shaft to th shuttle-body. In said drawings, or represents a shuttlebody of usual form and provided with a longitudinal chamber 12 in the top thereof and with an elongated slot 1) in its front portion, as illustrated in dotted lines in Figs. 1 and 2. In the shuttle-body and at one end of the chamber 19 is arranged a horizontal hole or recess 0, closed by a centrally-perforated plate or disk g, through which one end of the bobbin shaft or rod f is adapted to pass. Said shaft bears against the plate e, resting on the spiral spring d, arranged in said hole or recess. The other end of said shaft is bent upward at an acute angle, as at f, Fig. 4:, and is adapted to engage a vertically-arranged recess (0, having its inner back wall at an acute angle to its bottom. On said shaft is slidingly arranged the bobbin g, carrying the thread or threads '5, which bobbin is normally held and controlled by means of the spiral springs h and h, arranged on and surrounding the unoccupied portions of the shaft f. On the front portion of the shuttle-body a, and in alinement with the elongated slot 1), is secured in any desired manner the shuttle bow or conductor m, provided in. its culminating point with the horizontally-arranged eye m. Within said bow or conductor is arranged, and secured thereto by means of its depending ends 71. and M, a bridge n substantially parallel to the shaft f and provided in its center with an eye a. The ends a and n are each provided with an opening penetrated by its respective spiral spring 0 and 19, secured with their outer ends to and within the end portions of the bow or conductor, and are provided at their ends with loops 0 and 10, respectively, forming passages for the thread or threads 2'. Said thread or threads pass from the bobbin through eye 'n into and through loop 0, from whence into and through loop 19, and finally leave the shuttle after passing through the eye m in the bow or conductor m, as clearly shown in Fig. 1 of the drawings.

In placing the bobbin in position the rounded end of the shaft f is inserted through the perforated plate g into the recess 0, and the spiral spring is depressed sufficient to allow the insertion of the bent-up portion f of shaft f into the recess a. When said shaft is released, it remains locked within the chamber 1), as will be manifest. The spiral springs h and h will normally hold the bobbin in position, but are so adjusted that said bobbin can move from one side to the other, when the shuttle, for instance, is thrown over the race and is suddenly stopped in its movement by the box 011 the loom, by which arrangement breakage is avoided, and yet the proper tension is maintained. The spiral springs 0 and p serve also as take-up or tension devices, and thus prevent a breaking or looping of the thread, as will be manifest.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A loom-shuttle provided with a chamber in the upper side thereof, a shaft longitudinally arranged in said chamber and removably sccu red to the shuttle, a bobbin slidingly arranged on said shaft and adapted to revolve thereon, and a spiral spring surrounding said shaft and on each side of the bobbin and adapted to normally hold said bobbin in position, substantially as described.

2. A loom-shuttle, provided with a chamber in the upper side thereof, a horizontally-arranged recess in said shuttle and on one end of said chamber, an open slot or groove also in said shuttle and on the other side of said chamber, a shaft removably arranged in said recess and slot and adapted to support a bobbin Which latter is free to revolve and slidingly arranged on said shaft, and a spiral spring on each side of the bobbin and surrounding the shaft to normally hold said bobbin in position, substantially as described.

3. The combination with the shuttle-body provided in its front portion with an elongated slot, a bow or conductor on the front portion of the shuttle-bod y and in alinement with the elongated slot and provided with an eye, a bridge in said bow and also provided With an eye, a spiral spring on each side of the 0011- ductor and secured with its outer portion to and Within the said bow or conductor and penetrating with its inner portion the respective side of the bridge, and a loop on the inner end of each spiral spring, all said parts, substantially as and for the purposes described.

4c. The eombination with the shuttle-body and the bobbin carried thereby, of a bow or conductor at the front portion of the shuttlebody, and provided With an eye, a bridge traversing said bow and also provided with an eye, a spiral spring on each side of the conductor and secured With its inner end to and Within said conductor, and penetrating with its other end the bridge, and a loop on the-free end of each spiral spring, all said parts, substantially as and for the purposes described.

In testimony that I claim the foregoing I have hereunto set my hand this 17th day of October, 1896.

WALTER TODD.
